Working Theory

If you’re looking for performance capability without negatively affecting the environment, you should look into a Holden HSV plus 6 performance cat. Installing a high performance catalytic converter is one of many measures a car enthusiast will take to increase exhaust flow and thus gain added power. During the past years, developments in metallurgy and chemistry have enabled us to create high flow converters with exceptional output and reliability. free flow catalysts increase the engine power output throughout the rotational speed range. HP-gain is most notable at the wheels and also becomes exponentially larger as further modifications are made to the power source, such as cold intake, fuel controller or a catback exhaust system. Get rid of restrictive factory Holden HSV plus 6 catalytic converter that robs you of horses

Will the check engine light be triggered?

No, by any means, if converter is installed to the factory exhaust system then such an exhaust alteration made to the system would not cause the engine to run lean.

Contrary to the popular belief, converters are not commodities. There are huge differences in quality between brands, which results from the different raw materials that are used, manufacturing technology, coating materials, and numerous other factors. It is generally reasonable to assume that cheap cat converters are of lower quality, but that doesn't mean that the most expensive converters are the best. Torque in general, the power you feel in the seat while driving. Magnum Holden HSV plus 6 performance cat converters increase this torque as well as the performance throughout the engine rev range. As with output, the current increase isn't anything incredible, but the massive gains tend to improve as the rest of the car's power output. Magnum high flow catalytic converters feature engine specific gas restriction and vehicle specific inlet / outlet diameter. Your Holden HSV plus 6 performance cat converter will fit to factory piping. MIG/TIG/Flux required welding though. The improvement in technology in this industry has led to tuning brand companies being able to offer high flow catalysts that comply with the emission control regulations and bylaws in most of states and countries. Magnum catalytic converters will clean as well, if not better, than your stock cat.

Just because you respect the environment doesn't mean you can't put the pedal to the metal. Don’t want to harm the nature? When you weld in a performance catalyst, you can stay loyal to the environment while redlining your vehicle. Drive speedier with your Magnum performance cat. While the OEM converters are built with oversized ceramic substrate - that causes your performance and vigor to drop - this free flow cat features optimum gas restriction coupled with maximum performance. Take your Holden HSV plus 6's engine performance to its fullest potential with Magnum high flow catalytic converters. Don't hold your performance back with stock catalytic converters. If you're in the market for free-flow performance exhaust and highly enhanced engine potential, then this magnum Holden HSV plus 6 high flow cat converter is the ultimate solution. Your power capability will be through the roof.

These Holden HSV plus 6 free flow catalytic converters are built with both horses and harmful vapors in mind. Inside, our Holden HSV plus 6free flow catalysts are made with enormous ceramic substrates coated in max precious metals. Our manufacturing technology helps to strip out the more noxious fumes without employing undue restrictions like the factory cats. Internal catalyst’s honeycomb ceramic substrate maximizes the exhaust flow surface area for significantly reduced restrictions. While at first glance this cat looks like any other converter on the outside, the major difference is hidden in their bellies. Instead of being clogged with large restrictive honeycomb substrate, our low-restriction media gives the exhaust a clear path to your tailpipe. While harmful emission is neutralized, your power needs are totally satisfied.

Check out Magnum diameter specific high flow catalytic converters Additional technical background information Harmful compounds emitted by a 4-stroke engine The ideal combustion exists only in principle. An Otto-engine's efficiency is not better that 30 up to 45 %. Engine's efficiency and the amount of harmful emissions varies on several factors are related to the combustion taking place in the chambers. The theory described with chemical equation:

Ideal perfect combustion

CnH(2n+2) + O2 --- CO2 + H2O

Realistic combustion

CnH2(n+2) + O2 --- C + H2 + O2 + CO + CnH(2n+2) HC

Since the gas is polluted

N2 + O2 NOx

Pollution, additives

S + O2 SO2 + H2O + H2SO3 The carbon-oxide, nitro-oxides, hydrocarbons and the sulfuric-acids are deemed harmful, therefore their emission level is restricted by emission regulations in most of the countries. For over 30 years the most effective way to reduce the emission of harmful gases and materials to clean and neutralize the combustion products subsequently has been to purify the exhaust gas with one or more catalytic converters fitted on the vehicle's exhaust system.

Oxidation and Deoxidation within the catalytic converter

CO + (1/2)O2 --- CO2 CnH(2n+2) + O2 --- CO2 + H2O NOx + CO --- CO2 + N2 There is many other chemical reactions take place. When it comes down to attain the lowest emissions, electronic control over these chemical processes is a must. In modern engines catalytic converters are controlled electronically by exhaust oxygen sensor.

The oxygen sensor

An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, lambda sonda or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In most modern automobiles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel). This information is sent to the engine management ECU computer, which adjusts the mixture to give the engine the best possible fuel economy and lowest possible exhaust emissions.

Always check vehicle's all oxygen sensors before installing this cat. Each sensor has to be in good condition to have this converter working flawless.

This converter does not affect engine reliability or durability. It works well in conjunction with stock exhaust system and most of aftermarket exhausts. No CEL issue if magnum Performance Catalytic Converter is installed on stock exhaust system or in conjunction with a professional street legal aftermarket catback system or high flow exhaust muffler. Off-brand custom made / homemade catbacks and performance back mufflers may conflict. If so, highly recommended to wire up oxygen sensor simulator to the downstream - post oxygen sensor(s).

We strongly recommend having a certified tech install this performance exhaust.

Do not create stricture in tubing toward the tail end of exhaust. Any stricture results in power loss.

Claims correlate to factory condition engine. Defect or extensive wear and tear of related parts or systems can result in no or minimum effect.

Warranty voids if converter body or heat shield is damaged in any way.

Neither oxygen sensor nor oxygen sensor nut is included in the package.

Although Magnum performance cats fully comply with emission requirements of plenty of US states and countries even in California or European Community, they are not EPA (Environmental Protection Agency) certified also it is not Street Legal in California. Laws regarding replacement of catalytic converters are strict and vary by area. Please check regulations covering catalytic converter installation and replacement prior to purchase.

Dual exhaust with two catalytic converters in each bank requires two units.

This converter is a replacement of main catalytic converter and doesn’t necessarily replaces precat. Should you be uncertain this cat fits your needs, feel free to contact our product specialist.

not sneeze at this economy

Granted I purchased this Camaro used, the EPA highway estimate was 14 mpg, but on a recent trip after having cats welded on, I ran over 16 mpg consistently! For a 7 year old car with 160K miles, I will not sneeze at this economy! So far, so good

engine sounds and runs better

Magnum is a well trusted name in the tuning world. I had used their products in the past and decided to use one of their weld-on fit high flow converters on my Interpid 3.2. Fit is perfect once you have a good welder and a sawzall with a hacksaw blade sped up the removal. After replacement engine sounds and runs better. Overall I am very pleased with this converter.

The converter fit as described, and ive seen notable change of mid range power and a subtle improvement in mileage. My only critique is that as some have stated this is not bolt-on so you have to seek a certified exhaust fitter. In any other respect this is a real performance converter.
